The study examines the rates and types of school bus accidents according to the age of the school bus driver. Accident rates in North Carolina for the school year 1971-72 were analyzed using three sources of data: accident reports, driver and mileage data, and questionnaires administered to a sample of school bus drivers. Data were obtained on 10,508 drivers and an annual mileage of 74,110,890 miles. Results were analyzed statistically in the areas of: accident per driver age group, accident rates per million vehicle miles, accident severity, report categories, injury accidents, injuries by passenger miles, accident type, violations, location of accident, time of accident, weather and road conditions, driver experience, the other driver, and driver characteristics. Findings did not show a simple age-related curve. Student drivers (age 16 through 20 years) had a higher accident rate than adult drivers (age 21 and over) with 16-year olds having the highest rate and 20-year olds the second highest. The final 67 pages of the document contain 44 tables, graphs, a two-page bibliography, and eight appendixes (sample traffic accident and school bus accident reports, a sample school bus driver questionnaire, and supplemental statistical information on bus drivers).
